[Solved] RadAjaxManager/RadAjaxManagerProxy posting back the whole page for first click and not showing LoadingPanel

[nishant sagar]

adAjaxManager/RadAjaxManagerProxy refreshing the whole page for first click of any control attached with it and not showing odingPanel. from second click onwards it's behavior is normal as it is refreshing the content under updatedControls also showing the LoadingPanel. I am using Telerik.Web.UI(2009.2.826.20)

I have gone throough all the examples given for RadAjaxManager/RadAjaxManagerProxy and applied everything in my project.

Please tell me if I am missing anything. my code is as follows...

In First Attempt
<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
                        <AjaxSettings>
                            <telerik:AjaxSetting AjaxControlID="ddlOrganization">
                                <UpdatedControls>
                                    <telerik:AjaxUpdatedControl ControlID="RadGrid1" LoadingPanelID="ralPanel" />
                                    <telerik:AjaxUpdatedControl ControlID="RadGrid2" LoadingPanelID="ralPanel" />
                                    <telerik:AjaxUpdatedControl ControlID="errCtrl" LoadingPanelID="ralPanel" />
                                </UpdatedControls>
                            </telerik:AjaxSetting>
                            <telerik:AjaxSetting AjaxControlID="ddlTaskList">
                                <UpdatedControls>
                                    <telerik:AjaxUpdatedControl ControlID="RadGrid1" LoadingPanelID="ralPanel" />
                                    <telerik:AjaxUpdatedControl ControlID="RadGrid2" LoadingPanelID="ralPanel" />

Hello nishant,

The AJAX markup you posted seems fine. When AJAX settings do not work on first postback and start working from the second on, this usually indicates improper initialization of the AJAX settings. If you are declaring AJAX settings programmatically, make sure you create them not earlier than Page_Load. Creating AJAX settings earlier (on Init for example) will not work, as the AJAX manager is not initialized yet.

Alternatively, if you are using RadAjaxManagerProxy from a user control, share with us how do you load the user control with the proxy, as this, again, may be related to improper initialization of the AJAX settings.

Sincerely yours,
Veli
